Responding on Fox News today, Romney campaign manager Eric
Fehrnstrom compared Reid's comments to the infamous witch hunt of
Sen. Joe McCarthy, who suspected Communists of working in the
government.

"Those charges are untrue, they're baseless, and there's nothing
to back them up," Fehrnstrom said. "Again, this reminds me of the
McCarthy hearings back in the 1950s."

Fehrnstrom then referenced Joseph Welch, the head counsel for the
United States Army that confronted McCarthy.

"It was another son from Massachusetts, Joseph Welch, who asked
the question that now should be asked of Harry Reid," Fehrnstrom
said. "Which is, 'Have you no sense of decency, sir? Is
there nothing that you won’t do in the name of dirty
politics?'"
